Smokey and the Bandit. Only because it contains of one of my favorite movie lines. The sheriff(Jackie Gleason) to his bumbling, worthless deputy/son "Boy, I cannot believe you sprang from my loins. I oughta go home and punch your mother right in the face."

No one has mentioned a movie yet that's "so bad it's good." Everything you guys mention is "good enough to overcome its badness." But I got a keeper...

Cool As Ice This movie is so dumb that perhaps the most hilarious part of it is that it ever got made. (Unintentionally) funnier than most of the comedies you'll see at the theater.

Honorable mention:

Invaders From Mars (1986) Yeah, that's Nurse Ratched of "One Flew Over the Cuckoo's Nest" fame. The acting is wooden, the effects are silly and the end result is pure hilarity. Hard to believe that this is the same director that gave us "Poltergeist."

Leprechaun Somewhere in between roles as Willow and Harry Potter's Professor Flitwick, Hollywood's leading little man busted out a series of seriously cheesy horror flicks.

Red Dawn No doubt that when the Cubans finally invade and take over the US, they'll start by shooting 16-year olds at America's most rural high schools. Oh, and a shout-out to the NRA (and dangerousman), the Cubans will know which Americans to arrest by checking for your gun registration.

Commando: Has everything really, bad one-liners, Dan Hedaya as El Presidente, Arnold making short work of everybody and then has a hard time with Bennett, a noodle-armed pudge in leather pants who makes little squeaky noises when he fights. http://www.youtube.com/watch?v=uo_lCC97QXA

Streets of Fire: Is it bad? I don't know cuz I love it. Raven is probably my favorite Willem Dafoe character (maybe tied with Bobby Peru). Was Lee Ving even acting?

There's a whole slew of 'em but I think for me it's Troll. Just the first one. I know it must be bad because everyone tells me how bad it was but Phil Fondacaro was perfect as the human and the troll. And the Lockhart girls. And Sonny Bono. And Gary Sandy.

And JK gets away with stealing the Harry Potter idea from that movie. What's not to love?

I'm comfortably tipsy and I can't remember what made me think to look on Amazon. It's a guilty pleasure for me: Lost Horizon 1973. I've seen the old version also. Like both. The '73 version has been unavailable for years.
